While the male Red-winged Blackbirds perch on the fennel tops playing their trumpets, the females are starting work. The fresh new fennel is knee high in many places, waist high in some. It is dense enough to fill in the gaps between last year’s fennel stalks. Nests built in the new growth will be well concealed. This female gathered soft nesting material down in the fennel bottoms, and then briefly flew to the top and showed off her haul.
The blackbird population in the northwest quadrant of the park seems booming as the month of April advances.
